Anthropic’s AI security chief resigns, warns world is in danger

Serious concern expressed in mysterious letter

Mrinank has not directly named any company or person in his resignation letter. He wrote that the world is in danger not just from AI but from many interrelated crises. He said that the power of technology is increasing rapidly, but the understanding of how to handle it is not increasing that fast. If this continues, the entire humanity and society may have to bear its consequences for a long time.

Conflict between values ​​and pressure

Mrinank clearly said that under the constant pressure of work, the most important thing, i.e. values, were being left behind. He said that sometimes it becomes difficult to take right decisions even within the organization. He was pointing out that in the race to launch products faster and move ahead, AI safety may be compromised. For this reason, after introspection, they decided to separate.

Resignations have already taken place in the company

Mrinank’s resignation comes at a time when Anthropic has recently launched its new AI model and is preparing for funding. Even before this, some big names associated with the company’s research and AI safety team have resigned. Experts believe that this development shows that balancing safety and business goals is increasingly becoming a challenge for AI companies.
